Description

L'invention concerne un moyeu de roue de véhicule automobile comportant un palier à corps roulants disposé dans un logement dudit moyeu et un dispositif capteur d'informations dont l'élément codeur est solidaire en rotation du moyeu et se déplace devant un capteur fixe.The invention relates to a wheel hub of a motor vehicle comprising a rolling body bearing disposed in a housing of said hub and an information sensor device the encoder element of which is integral in rotation with the hub and moves in front of a fixed sensor.

La publication FR.A.2 570 143 décrit un tel moyeu dans lequel l'élément codeur est fixé à la périphérie externe du moyeu sensiblement dans le plan d'un chemin de roulement du palier.The publication FR.A.2 570 143 describes such a hub in which the encoder element is fixed to the external periphery of the hub substantially in the plane of a raceway of the bearing.

Lorsque le moyeu est solidaire d'un tambour de freinage qui délimite avec la périphérie externe du moyeu le logement de frein, l'élément codeur ne peut plus être placé sur le moyeu. Par ailleurs, lorsque le palier à corps roulants est un roulement conventionnel placé dans un moyeu accolé au porte-fusée sur lequel est fixé le plateau de frein, le dispositif capteur ne peut plus satisfaire à l'agencement précité, en raison du faible espace disponible.When the hub is integral with a brake drum which defines the brake housing with the outer periphery of the hub, the encoder element can no longer be placed on the hub. Furthermore, when the rolling body bearing is a conventional bearing placed in a hub attached to the stub axle on which the brake plate is fixed, the sensor device can no longer satisfy the above arrangement, due to the small space available. .

L'invention a donc principalement pour objet un moyeu de roue pour freins à tambour facilitant le montage d'un capteur de vitesse dans le but de permettre par exemple, la réalisation d'un dispositif d'antiblocage de roues et/ou d'antipatinage pour véhicules équipés de freins à tambour.The invention therefore mainly relates to a wheel hub for drum brakes facilitating the mounting of a speed sensor in order to allow for example, the realization of an anti-lock device and / or traction control for vehicles fitted with drum brakes.

Selon l'invention, l'élément codeur est intégré de préférence dans le joint d'étanchéité du palier à corps roulants de telle façon qu'il affleure sensiblement dans le plan d'une face latérale du moyeu tournée vers le plan longitudinal du véhicule, l'élément capteur, solidarisé avec un support fixe par rapport à la roue, étant disposé coaxialement à l'élément codeur dans une position radiale sensiblement égale à la valeur du rayon de l'élément codeur et décalée longitudinalement d'une valeur maximale correspondant à l'entrefer autorisé par la technologie du capteur mis en oeuvre.According to the invention, the encoder element is preferably integrated in the seal of the rolling body bearing so that it is substantially flush with the plane of a lateral face of the hub facing the longitudinal plane of the vehicle, the sensor element, secured to a fixed support relative to the wheel, being arranged coaxially with the encoder element in a radial position substantially equal to the value of the radius of the encoder element and offset longitudinally by a maximum value corresponding to the air gap authorized by the sensor technology used.

On décrira ci-après un mode de réalisation du moyeu en référence au dessin annexé dans lequel,

  • - la figure 1 est une vue en coupe axiale du moyeu de frein à tambour monté sur une fusée de roue non motrice de véhicule automobile selon la ligne 1.1. de la figure 2.
  • - la figure 2 est une vue de face du moyeu suivant la flèche F de la figure 1.
  • - la figure 3 est une vue à une plus grande échelle du détail III de la figure 1.
  • - la figure 4 est une vue à une plus grande échelle du même détail III avec un agencement différent de la liaison entre le capteur et son sup­port.
An embodiment of the hub will be described below with reference to the appended drawing in which,
  • - Figure 1 is an axial sectional view of the drum brake hub mounted on a non-driving wheel spindle of a motor vehicle along line 1.1. in Figure 2.
  • FIG. 2 is a front view of the hub according to arrow F in FIG. 1.
  • - Figure 3 is a view on a larger scale of detail III of Figure 1.
  • - Figure 4 is a view on a larger scale of the same detail III with a different arrangement of the connection between the sensor and its support.

Un moyeu de roue non motrice comporte une fusée 10 débouchant à l'exté­rieur d'un porte-fusée 11 et portant à son extrémité filetée, l'écrou 12 et la rondelle de mise en contrainte axiale d'un palier 13 qui peut être à deux rangées de corps roulants 14 disposés entre une bague intérieure 15 fractionnée en deux parties et une bague extérieure 16 dont les extré­mités portent respectivement un joint d'étanchéité 17.A non-driving wheel hub comprises a spindle 10 emerging outside of a stub axle 11 and carrying at its threaded end, the nut 12 and the axial stress washer of a bearing 13 which may be at two rows of rolling bodies 14 arranged between an inner ring 15 divided into two parts and an outer ring 16, the ends of which carry a seal 17 respectively.

Le palier 13 peut être constitué de 2 roulements conventionnels sans sortir pour autant du cadre de la présente invention.The bearing 13 can consist of 2 conventional bearings without thereby departing from the scope of the present invention.

Le palier 13 est disposé dans un logement 21 constitué par l'alésage d'un moyeu tournant 20 qui se prolonge radialement par un tambour de frein 23 dont la face extérieure porte les goujons de fixation non représentés de la roue du véhicule.The bearing 13 is disposed in a housing 21 formed by the bore of a rotating hub 20 which is extended radially by a brake drum 23 whose outer face carries the not shown fixing studs of the vehicle wheel.

La bague extérieure 16 du palier est immobilisée dans le moyeu 20, radialement par serrage et axialement entre un épaulement 24 du logement 21 et une rondelle d'arrêt portée par le moyeu.The outer ring 16 of the bearing is immobilized in the hub 20, radially by clamping and axially between a shoulder 24 of the housing 21 and a locking washer carried by the hub.

Selon l'invention, un dispositif capteur 25 d'informations, notamment de la vitesse de rotation de la roue, est constitué par un élément codeur 26 solidaire en rotation du moyeu 20 et d'un capteur 27 fixe. L'immobilisa­tion de l'élément codeur 26 est avantageusement réalisée par intégration au joint d'étanchéité 17 au moment du moulage de ce dernier de telle façon qu'il soit positionné en regard de l'élément capteur. Tel que repré­senté dans la fig. 1, l'élément codeur affleure la face latérale externe du joint d'étanchéité. Selon une variante de l'invention (fig. 4), le support 28 du codeur 26 est une bague comportant une rainure circulaire dans laquelle est logé l'élément codeur 26 et ce support est placé dans le loge­ment 21 de sorte que le codeur soit situé sensiblement dans le plan de la face latérale 22 du moyeu tournée vers le plan longitudinal du véhicule. Le support 28 possède à cet effet, un bord 30 radial annulaire susceptible de faciliter son immobilisation par pincement entre le flanc de la bague 16 du palier et l'épaulement 24.According to the invention, an information sensor device 25, in particular of the speed of rotation of the wheel, is constituted by an encoder element 26 integral in rotation with the hub 20 and a fixed sensor 27. The immobilization of the encoder element 26 is advantageously carried out by integration to the seal 17 at the time of molding of the latter so that it is positioned opposite the sensor element. As shown in fig. 1, the encoder element is flush with the external lateral face of the seal. According to a variant of the invention (fig. 4), the support 28 of the encoder 26 is a ring having a circular groove in which is housed the encoder element 26 and this support is placed in the housing 21 so that the encoder is located substantially in the plane of the lateral face 22 of the hub facing the longitudinal plane of the vehicle. The support 28 has for this purpose an annular radial edge 30 capable of facilitating its immobilization by pinching between the side of the ring 16 of the bearing and the shoulder 24.

La solidarisation entre l'élément codeur et son support peut être réalisée par d'autres moyens sans pour autant sortir du cadre de l'invention.The connection between the encoder element and its support can be achieved by other means without departing from the scope of the invention.

Le support 29 de l'élément capteur 27 est constitué par une plaque en matériau de préférence non magnétique, rendue solidaire d'une bague 30′ fixe montée sur la fusée 10 entre la bague intérieure 15 du palier et le porte-fusée 11. Le support 29 est agencé de telle façon que son positionne­ment angulaire par rapport au plateau de frein soit assuré. Dans l'exemple représenté fig. 2, le support 29 comporte une série d'encoches 31 qui assurent cette fonction en coopérant avec les vis de fixation 33 du plateau de frein 32. Par ailleurs, le support 29 est conçu de telle façon qu'il n'existe qu'une seule et unique possibilité de positionnement angulaire favorable au fonctionnement correct de l'élément capteur 27. De manière à s'affranchir de la variation d'entrefer entre l'élément codeur 26 et l'élé­ment capteur 27 engendrée par le dévers angulaire de la roue selon son plan de symétrie vertical durant les virages, l'élément capteur 27 est positionné selon une direction horizontale A - A′ telle que représentée en fig. 2.The support 29 of the sensor element 27 consists of a plate of preferably non-magnetic material, made integral with a fixed ring 30 ′ mounted on the spindle 10 between the inner ring 15 of the bearing and the stub axle 11. support 29 is arranged in such a way that its angular positioning relative to the brake plate is ensured. In the example shown in fig. 2, the support 29 comprises a series of notches 31 which perform this function by cooperating with the fixing screws 33 of the brake plate 32. Furthermore, the support 29 is designed in such a way that there is only one one and only possibility of angular positioning favorable to the correct functioning of the sensor element 27. In order to overcome the variation in air gap between the encoder element 26 and the sensor element 27 generated by the angular cant of the wheel according to its vertical plane of symmetry during the turns, the sensor element 27 is positioned in a horizontal direction A - A ′ as shown in fig. 2.

Le support 29 de l'élément capteur 27 a pour fonction complémentaire de supporter un circuit imprimé 27′ comprenant les éléments de protection de l'élément capteur 27 contre les surtensions et les inversions de polarité. En outre, il assure le maintien efficace du câble 27˝ qui transporte les signaux vers la centrale de traitement en traversant le plateau de frein 32, en coopérant avec un élément 34 qui assure l'étan­chéité contre la pénétratïon de pollution à l'intérieur de l'enceinte du frein.
Sans sortir du cadre de l'invention, il est bien évident que le dispositif capteur 25 peut être de tout type connu, bien que l'on ait décrit à titre d'exemple aucunement limitatif, le capteur en référence de la demande de brevet 86.08348 déposée en France au nom de la demanderesse.
The support 29 of the sensor element 27 has the additional function of supporting a printed circuit 27 ′ comprising the elements for protecting the sensor element 27 against overvoltage and reverse polarity. In addition, it ensures the effective maintenance of the 27˝ cable which transports the signals to the central processing unit while crossing the brake plate 32, by cooperating with an element 34 which seals against the penetration of pollution inside the brake chamber.
Without departing from the scope of the invention, it is obvious that the sensor device 25 can be of any known type, although the sensor with reference to patent application 86.08348 has been described by way of non-limiting example. filed in France in the name of the plaintiff.

De même, l'invention n'est nullement limitée au mode de réalisation décrit et représenté, donné à titre d'exemple. En particulier, elle englobe les moyens équivalents techniques des moyens décrits ou leurs combinaisons si celles-ci réalisées dans l'esprit de l'invention ou mises en oeuvre dans le cadre d'une prise d'informations de la vitesse d'un moyeu tournant.Likewise, the invention is in no way limited to the embodiment described and shown, given by way of example. In particular, it includes the equivalent technical means of the means described or their combinations if these carried out in the spirit of the invention or implemented in the context of taking information about the speed of a rotating hub .
